Heat pipe type solar collector and sealing structure thereof

The invention relates to a solar collector, in particular to a sealing structure of a heat pipe type solar collector.

In the current application of solar radiant heat, solar collectors are relatively commercial and economical products. In order to improve the conversion efficiency of solar radiant heat, heat pipes with excellent heat transfer capacity are applied to solar collectors. The components that transfer heat have achieved good results.

Please refer to the first figure and the second figure, which are schematic diagrams and cross-sectional views of the current heat pipe type solar collectors. In the first figure, the heat pipe type solar collector sealing structure 1a includes a heat exchange tube body 10a, and inserts The plurality of tubes 20a connected to the heat exchange tube body 10a and the plurality of heat tubes 30a piercing the tubes 20a. When the sealing structure 1a of the heat pipe type solar collector is used, the cold water flows from the one end of the heat exchange tube body 10a, flows through the heat pipes 30a, and carries away the heat of the heat pipes 30a, and then from the heat exchange pipe body. The other end of 10a flows out.

When the heat pipe type solar heat collector 1a is disposed, a plurality of through holes 11a are first opened in the heat exchange tube body 10a, and then the plurality of branch pipes 20a are welded in the through holes 11a, and finally, The heat transfer medium 40a is coated on the inner walls of the branch pipes 20a, and the heat pipes 30a are closely penetrated in the through holes 11a.

The heat exchanger type solar heat collector 1a is not only complicated and time consuming, but also has a possibility of leakage at the welded portion. Further, since the heat pipes 30a perform heat exchange, they do not directly contact the water in the heat exchange tube body 10a. Rather, it is indirectly transmitted to the heat exchange tube body 10a through the branch pipes 20a, so that the heat transfer efficiency is greatly reduced and needs to be improved.

In view of the above, the present inventors have made great efforts to study and cooperate with the application of the theory, and finally propose a present invention which is reasonable in design and effective in improving the above-mentioned defects.

An object of the present invention is to provide a sealing structure of a heat pipe type solar collector to maintain the sealing property when the heat exchange tube body is combined with the heat pipe and to improve the heat exchange effect.

In order to achieve the above object, the present invention is a heat pipe type solar collector, comprising a heat exchange tube body, a piercing sleeve, a sealing plug ring, and at least one heat pipe, wherein the heat exchange tube body has a receiving space and heat One side of the exchange tube body is provided with a screw hole that does not penetrate the wall of the tube and at least a consistent hole that communicates with the accommodating space. The through sleeve includes a column with a perforation, and the heat pipe is inserted through the hole. The outer peripheral surface has a plurality of threads and is screwed into the screw hole. The sealing plug ring comprises a ring sleeve sleeved on the heat pipe and a ring piece extending outward from the outer edge of the ring sleeve, the ring piece being forced by the pipe string The through hole is penetrated, and one end of the heat pipe is disposed in the heat exchange tube body through the through sleeve and the sealing plug ring.

In order to achieve the above object, the present invention is a heat pipe type solar collector sealing structure for combining a heat exchange tube body and a heat pipe, and one side of the heat exchange tube body is provided a threaded hole not penetrating through the wall of the tube and a consistent hole in the threaded hole, the sealing structure comprises a through sleeve and a sealing plug, the through sleeve includes a column with a perforation, and the through hole is pierced The heat pipe has a plurality of threads on the outer edge surface of the pipe string and is screwed into the screw hole. The sealing ring comprises a ring sleeve sleeved on the heat pipe and a ring piece extending outward from the outer edge of the ring sleeve. The plug is placed in the perforation, and the ring piece is forced by the pipe string to abut the through hole, wherein one end of the heat pipe is disposed in the heat exchange pipe body through the piercing sleeve and the sealing plug ring.

Another object of the present invention is to provide a sealing structure of a heat pipe type solar heat collector. Since the sealing structure has a sealing ring, the through sleeve is pressed against the ring piece and the sealing ring of the sealing ring, thereby maintaining the wearing. Sealing between the sleeve and the through hole to prevent water from flowing out inside the heat exchange tube.

Compared with the prior art, the collector of the present invention tightly couples the heat pipe in the heat exchange tube body through the sealing structure, and maintains the sealing property between the two, and can be arranged by the piercing sleeve. Simplifying the manner of bonding the heat pipe to the heat exchange tube; in addition, since the sealing structure includes a sealing ring, it provides a tight sealing effect, ensures sealing and effectively prevents leakage; further, compared with the conventional The heat pipe uses heat transfer by indirect conduction. The heat pipe of the present invention directly contacts the water in the heat exchange tube, so the heat transfer efficiency is high and the heat collecting effect is good, and the utility of the present invention is further increased.
